Abstract
A tray type spraying deduster is disclosed. The tray type spraying deduster comprises a gas inlet, a gas outlet, a circulating slurry pool, downward-inclined flow plates, upward-inclined flow plates, a spraying device, demisters, a circulating pump, a gypsum discharging pump and guiding blades. The top of the deduster is provided with the gas outlet. The side wall of the lower part of the deduster is provided with the gas inlet. The demisters, the dedusting device, the inclined flow plates and the circulating slurry pool are disposed in the deduster from up to down in sequence. The demisters are baffle-plate demisters. The inclined flow plates comprise 2-5 groups, and each group comprises the downward-inclined flow plate and the upward-inclined flow plate. The upward-inclined flow plates are above the corresponding downward-inclined flow plates and are disposed in an opposite inclined manner. A plurality of the groups of the inclined flow plates form a zigzag pattern. Side edges of the inclined flow plates are provided with the guiding blades. The guiding blades are disposed in a circuitous manner. The deduster increases the desulphurization and dedusting efficiency. Because arrangement of the deduster is simple, reconstruction of an original hollow tower spraying deduster is convenient.
Description
Technical field
The present invention relates to chemical industry dedusting field, particularly relate to a kind of column plate type spray deduster.
Background technology
Hollow tower desulfurizing dust-collector is able to extensive use as smoke dust-removing equipment at a lot of industrial circles, and sprayed slurry contacts with sulfur-containing smoke gas in tower by high-pressure pump, and the sulphur in flue gas is dropped into recycle slurry pond under being absorbed by solution, thereby reaches the effect of desulfurization.Existing hollow tower desulfurizing dust-collector relies on the rising voluntarily of flue gas by spray, to carry out desulfurization more mostly, and this gas-liquid contact time and area are limited, and desulfuration efficiency is limited to.
Summary of the invention
The present invention is exactly the problem existing for the said goods, a kind of column plate type spray deduster is provided, the existing hollow tower desulfurizing dust-collector that solves the said goods existence relies on the rising voluntarily of flue gas by spray, to carry out desulfurization more mostly, this gas-liquid contact time and area are limited, and desulfuration efficiency such as is limited at the problem.
The present invention adopts following technical scheme: a kind of column plate type spray deduster, comprise air inlet, gas outlet, circulation stock tank, lower oblique flow plate, upper oblique flow plate, spray equipment, demister, circulating pump, gypsum excavationg pump, guide vane, described dust remover roof sets out gas port, lower sides is provided with air inlet, inside is provided with demister successively from the top down, spray equipment, oblique flow plate, circulation stock tank, described demister is deflection plate demister, described oblique flow plate quantity is two to five groups and every group and consists of upper oblique flow plate and lower oblique flow plate, upper oblique flow plate is positioned at top and the relative tilt setting of lower oblique flow plate, the word shape that many group oblique flow plates are, the side of oblique flow plate is established guide vane, the roundabout setting of described guide vane, guiding flue gas is by roundabout rising after moisture film.On described spray equipment, fixedly establish splashing type nozzle, in described circulation stock tank, have lime slurry, circulation stock tank peripheral hardware circulating pump and gypsum excavationg pump.
Operation principle of the present invention: dusty gas is entered and flowed to tower top in tower by deduster bottom air inlet, oblique flow plate through winding type, the alkaline solution stream that spray equipment falls is on upper oblique flow plate, the downward oblique flow plate of flow of solution being fallen by upper oblique flow plate, the cascade that flow liquid falls along formation through oblique flow edges of boards, gas also needs by cascade in roundabout making progress, SO
2by alkaline solution, absorbed and reach purification object, the guide vane being provided with prevents that flue gas from crossing oblique flow plate and passing through from oblique flow plate side, circulating pump pumps by lime slurry the nozzle that is delivered to spray equipment by slurries pipeline and sprays downwards, it is moistening and trap that flue dust and flying dust are recycled liquid, slurries fall into the circulation stock tank of gas wash tower bottom, the thick slurry of circulation stock tank bottom is discharged through gypsum excavationg pump, top alkaline slurry again enters slurries pipeline and discharges, and is discharged gypsum and is added lime slurry to carry out the pH value of controlled circulation stock tank simultaneously by pump.
The present invention compared with prior art, there is following beneficial effect: the roundabout and eddy flow setting of described a kind of column plate type spray deduster has increased time of contact and the area between gas-liquid, gas has not only increased roundabout distance but also need to be by flowing down the cascade of formation from oblique flow plate when roundabout rising, thereby has improved the efficiency of desulfurization and dedusting.In addition, simple owing to arranging, for original hollow tower spray deduster also convenient transformation.
